PAD LOCK.

SPECIFICATION forming part of Letters Patent No. 513,160, dated January 23, 1894. Application filed September 5, 1892. Serial No. 445,142. on more.)

To all whom it may concern.-

Be it known that we, WILLIAM F. TROAST and SAMUEL R. SLAYMAKER, citizens of the United States, residing in Lancaster, in the county of Lancaster and State of Pennsylvania, have invented certain Improvements in Padlocks, of which the following is a specification.

This invention relates to improvements in that class of .padlocks in which one end of a U-shaped shackle is pivoted in the case; and the objects of theinvention are, first, to guard more thoroughly against the surreptitious opening of the lock than is done in the padlocks now in use; and second, to prevent transverse motion of the swinging. end of the shackle when locked in the case.

The invention consists in the construction and combination of the various parts, as hereinafter fully described, and then specifically pointed out in the claims.

In the accompanying drawings, which form a part of this specification, Figure 1 is a bottom perspective view of the body of the case, the cap being removed and the operating mechanism shown in place with the shackle locked in the case. Fig. 2 is a top perspective view of the body of the case, showing the operating mechanism in place, the swinging end of the shackle locked therein and the top plate of the case cut away to show the position of the bolt-spring. Fig. 3 is a perspective bottom view of the same part of the case, showing the shackle opened out and the plunger head in position in front of the bolt. Fig. 4 is a top perspective view, showing the shackle opened out and the top plate cut away to show the position of the bolt-spring when the shackle is so opened. Fig. 5 is a perspective view of the body of the case, showing the operating parts removed. Fig. 6 is a similar view of the cap, as seen from the top. Fig. 7 is a lower side perspective view of the bolt, and Fig. 8 an upper side perspective view thereof. Fig. 9 is a perspective view of the plunger.

Similar letters and figures indicate like parts throughout the several views.

The lock-case is divided edgewise or approximately so, through the center, one side A, called the body of the case for the 'purposes of this specification, having the rivetpins a and a formed therewith and the operating mechanism located therein. The fastlimb of the shackle Bis pivoted on rivet-pine, and-the space occupied by the end of said fast limb is separated from the body by registering walls E, formed about said space in the body A and cap A. (The portion A is called the cap for the purposes of this specification.) These walls prevent the entrance of any foreign matter into the case through the spaces between the said fast end of the shackle and the sides of the case. The swinging end of the shackle has a reduced end I), in the inner edge of which there is formed a notch b. In the upper end of the case there is achannel formed between the top plate a of the body'of the case anda wall 9, f and 10 therein and a wall 23 registering therewith formed with cap A. In this channelthere is placed a locking-bolt 0. Bolt 0 is of peculiar construction. In the lower face there is an oval opening 1, in the upper right-hand cornerof which is formedashoulder 2, as shown in Fig. 7, adapted to be engaged by a ward of the key to force the bolt 0 back out of engagement with the shackle. The upper end of opening 1 is partially covered by flanges or partitions 3, forming a winged-opening between them through which the heel of the key passes, said flanges or partitions being engaged by corresponding notches in the key. On the ends of both longitudinal edges of said bolt there are lugs 4:, which bear against the inner faces of the body of the case and the cap thereof. One end of bolt 0 is provided with a'tongue, 5, adapted to enter the notch'b in the reduced endb of the swinging arm of the shackle, and on the inner edges of this tongue there are formed lips 6, constructed to embrace the portion of end 5 below said notch, thereby preventing anytransverse motion of the swinging end of the shackle and looking it more securely with the bolt. Adjoining tongue 5 on the upper face of bolt 0 there are studs or pins 7, and around these studs and between the same and the offset or shoulder formed by tongue 5, there is bent the headD of the flat bolt spring, the leaves d of which extend lengthwise over the said upper face of bolt 0, being prevented Ioo from closing upon each other by a stay 8, formed on the end of the bolt opposite to that on which studs 7 are placed.

Stay 8 is not essential to the proper working of the bolt-spring, for when the vibrating ends of said spring meet the opening between them increases in width from said ends to the head D, leaving sufficient space between them for the introduction of the flat key used,but it facilitates the introduction of the key by increasing the opening between leaves d, and it is therefore preferable to employ it.

When the bolt C is engaged with the swinging end of the shackle the ends of leaves d, passing through slotse in walls E, abut against the inner edge of the fast end of the shackle and form struts that afford a positive resistance to the accidental disengagement of the bolt from said swinging end. In unlocking the shackle the key spreads the leaves cl of the bolt-spring and frees the ends from engagement with the fast end of the shackle and as it moves the bolt back causes said leaves to embrace opposite sides of said fast end, recesses 6' being formed in the body of the case and the cap to receive the ends of said leaves. In addition to the bolt spring there is a spring 12 coiled about a post 11 formed in the body of the case and passing over the reduced wall 9 and having one arm bearing against the wall E and the other against the back end of bolt 0 to force said bolt into engagement with the swinging end of the shackle.

The key-guide F is of a construction l1eretofore patented. In this look the upper transverse part f forms a portion of the wall serving to hold the bolt G in place and also serves as a ward to engage corresponding notches in the key. In the front of this key-guide there is an annular recess f in which there is a key-hole guard f having a slot f through which the key passes.

On the side of the case in which the swinging end of the shackle is locked there is a plunger having an enlarged semi-circular head 13, which bears against the end of the swinging arm of the shackle and forces the same out of the case when released from bolt 0. The stem 16 of the plunger passes through an opening 17 in the part 10 of the wall forming the bolt channel and has formed thereon, below said wall, a boss 18. Below said boss there is a circular extension, 19, of stem 16, around which there is coiled a spring 20, one end of which bears against boss 18 and the other against the bottom of arecess 21 formed in the bottom of the case. In the ends of the vertical edge of the plunger head there are formed notches 14, which engage ribs 15 in the body and cap of the case and thus control the movement of the plunger, which, to be fully efiective must act vertically against the swinging end of the shackle.

The cap A of the case is provided with walls 24:, that register with the walls of keyguide F; and from one of these walls there extends a wall or stay 25, which holds spring 12 down in place. There are also apertures 22 through cap A adapted to be engaged by the rivet pins or and (1,.
